To our knowledge, this is simply the best filter you can buy for the money.
We know because a major Volvo owners club dissected 13 name-brand oil filters to evaluate and compare quality.
This filter manufactured by Mann® grabbed the number one slot. Mann is the original supplier of oil filters to Volvo.
Mann filters are one of the few on the market that have a "check valve" that reduces the amount of oil that drains back in to the sump when the engine is shut off. The helps supply oil to top areas of the engine faster on cold starts.
